  • A UNIQUE FLUID DIVERTER DESIGN FOR WATER

    nozzle design has to guarantee that within the whole flow rate range a full, not splashing water jet is formed with a nearly rectangular cross-sectional area. To achieve this goal, a variable cross section of the nozzle’s outlet is necessary. Besides the jet stream the diverter has to be absolutely tight. Win-
